Type in the a, b, and c, values of any quadratic equation. If it is solvable, then the Scratch cat will tell you the x equivalents. The program factors the equation if it is factorable, and uses the quadratic formula if it isn't. If it is not solvable, then the Scratch cat will say "No real solutions" and tell you the discriminant (b^2 - 4ac). Press space to show or hide the variables. Let me know in the comments if you find any bugs. Feel free to use parts of the code for other projects, as long as you give credit. :) Also, ignore the list names, since they're only accurate for some of the functions.
